    • Les figures 1 à 3 représentent un mode de réalisation d'un dispositif 1 d'oxycoupage de brames 2 avec deux postes de travail, à l'aide d'au moins un chalumeau d'oxycoupage 3 selon l'invention, en vue de face et vue latérale, dans différents états d'utilisation, soit au repos sans brame, en service pour l'oxycoupage d'une brame sur le poste gauche, le poste de droite étant déjà chargée d'une autre brame 2 à couper, et en service pour l'oxycoupage de la brame 2 sur le poste de droite, une brame 2, venant d'être coupée sur le poste de gauche, étant prête pour être enlevée.Figures 1 to 3 show a mode of production of a device 1 for flame cutting 2 with two work stations, using at least one blowtorch flame cutting 3 according to the invention, in front view and view side, in different states of use, i.e. slab-free rest, in service for flame cutting a slab on the left post, the right post is already loaded another slab 2 to be cut, and in service for the flame cutting of slab 2 on the right post, a slab 2, having just been cut on the left post, being ready to be removed.

    Chaque poste de travail comprend un cadre support 4 basculable entre une position horizontale (non montrée) et une position inclinée sous un angle par rapport à la verticale de -20° à -10°, de préférence -15°, ainsi que représenté dans les figures 1 à 3.Each workstation includes a frame support 4 tiltable between a horizontal position (not shown) and a tilted position at an angle to it vertically from -20 ° to -10 °, preferably -15 °, as well as shown in Figures 1 to 3.

    Sur le cadre support 4 on trouve plusieurs paires de rouleaux 5, 6 montés en équerre servant à recevoir une brame 2 sur chant sur les rouleaux inférieurs 6, les rouleaux 5 formant un plan d'appui oblique pour une brame 2 à couper. Ces paires de rouleaux 5, 6 de chaque poste de travail sont chacune mobile le long de l'extension longitudinale du cadre support 4 associé en utilisant des moyens appropriés connus par l'homme de l'art. Ceci permet de placer chaque paire de rouleaux 5, 6 à l'endroit approprié où ils ne gênent pas l'opération du chalumeau d'oxycoupage 3 pour couper la brame 2 reposant sur les rouleaux inférieurs 6 sur chant et sur les rouleaux 5 formant le plan d'appui oblique.On the support frame 4 there are several pairs of rollers 5, 6 mounted at an angle used to receive a slab 2 on edge on the lower rollers 6, the rollers 5 forming an oblique support plane for a slab 2 to be cut. These pairs of rollers 5, 6 of each workstations are each mobile along the extension longitudinal of the associated support frame 4 using suitable means known to those skilled in the art. this allows place each pair of rollers 5, 6 at the place suitable where they do not interfere with the operation of the torch flame cutting 3 to cut the slab 2 resting on the lower rollers 6 on edge and on rollers 5 forming the oblique support plane.

    Au moins une paire de règles 7, 8 montées par des moyens appropriés en cavalier sur le cadre support 4 pour être mobiles le long de l'extension du cadre support 4 de chaque poste du dispositif 1 d'oxycoupage de brames 2 en direction de la double flèche 9, reçoivent ledit au moins un chalumeau d'oxycoupage 3 et l'autre ledit dispositif d'ébavurage (non représenté) associé au chalumeau d'oxycoupage. Le chalumeau d'oxycoupage 3 et son dispositif de d'ébavurage associé se trouvent l'un en face de l'autre et de part et d'autre des rouleaux 5; en service la brame 2 à couper se trouve entre eux.At least one pair of rules 7, 8 mounted by appropriate means on the support frame 4 to be mobile along the extension of the support frame 4 of each station of the slab flame cutting device 1 in direction of the double arrow 9, receive said at least one flame cutting torch 3 and the other said device deburring (not shown) associated with the blowtorch flame cutting. The flame cutting torch 3 and its device associated deburring are located opposite each other and on either side of the rollers 5; in service the slab 2 to cut is between them.

    La chalumeau d'oxycoupage 2 et son dispositif d'ébavurage associé sont mobiles le long de leur règle 7, 8 respective en direction de la double flèche 10. En service sur une brame à couper 2, le chalumeau coupe la brame 2, transversalement à son extension longitudinale; la brame 2 est débitée.The flame cutting torch 2 and its device associated deburring are movable along their rule 7, 8 in the direction of the double arrow 10. In service on a slab to be cut 2, the torch cuts the slab 2, transversely to its longitudinal extension; slab 2 is debited.

    L'opération de découpage de brames se passe comme suit: Un des cadres support 4 est rabattu dans la position horizontale. Une brame 2 à couper est chargée à l'aide d'un moyen de manutention appropriée, c-à-d. de levage ou pousseur sur les rouleaux 5 jusqu'à toucher les rouleaux 6. Le cadre support 4 est basculé dans la position de coupe faisant un angle de -20° à -10° par rapport à la verticale, de préférence 15°. Le chalumeau d'oxycoupage 2 est déplacé le long de l'extension longitudinale du cadre 4 à l'endroit de la brame 2 ou celle-ci est à couper. Si le chalumeau d'oxycoupage 2 et son dispositif d'ébavurage associé doivent alors se trouver à l'endroit de l'espace libre entre deux paires de rouleaux 5, 6. Si tel n'est pas le cas, le ou les paire(s) de rouleaux 5, 6 qui gênent le fonctionnement du chalumeau 2 doivent être ajustées le long du cadre support 4 de sorte à ne plus gêner l'opération d'oxycoupage. Le chalumeau d'oxycoupage 3 et son dispositif d'ébavurage sont déplacés le long des règles 7, 8 jusqu'au bord supérieur ou inférieur de la brame 2 et l'opération d'oxycoupage est démarrée. Ensuite le chalumeau 3 et son dispositif d'ébavurage sont déplacés dans la direction de la double flèche 10 vers le bord opposé inférieur ou supérieur de la brame 2 et l'opération d'oxycoupage est terminée, quand le bord opposé est atteint.The slab cutting operation takes place as follows: One of the support frames 4 is folded down in the horizontal position. A slab 2 to be cut is loaded at using appropriate handling means, i.e. of lifting or pushing on the rollers 5 until touching the rollers 6. The support frame 4 is tilted in the position cutting angle from -20 ° to -10 ° to the vertical, preferably 15 °. The flame cutting torch 2 is moved along the longitudinal extension of frame 4 at the location of slab 2 where it is to be cut. If the flame cutting torch 2 and its deburring device associated must then be at the place of space free between two pairs of rollers 5, 6. If not the case, or the pair (s) of rollers 5, 6 which obstruct the torch 2 operation must be adjusted along of the support frame 4 so as no longer to interfere with the operation flame cutting. The flame cutting torch 3 and its device deburring are moved along rules 7, 8 until upper or lower edge of slab 2 and the operation oxygen cutting is started. Then torch 3 and its deburring device are moved in the direction of the double arrow 10 towards the opposite lower edge or top of slab 2 and the flame cutting operation is finished, when the opposite edge is reached.

    Pendant le temps qui s'est passé jusqu'à l'arrêt de l'oxycoupage de la brame 2, une autre brame 2 a été chargée sur le second poste de travail suivant la procédure qui vient d'être décrite. L'opération d'oxycoupage de la première brame 2 terminée, les règles 7, 8 sont déplacées avec le chalumeau d'oxycoupage 2 et le dispositif d'ébavurage vers l'autre poste de travail dont le cadre de support 4 forme un angle identique par rapport à la verticale que le cadre support 4 du premier poste de travail sur lequel l'opération d'oxycoupage vient de se terminer. Ainsi lesdites règles 7, 8 peuvent être déplacées en cavalier sur le cadre support 4 de l'autre poste de travail à l'endroit où la brame 2 chargée doit être découpée et les mêmes opérations de contrôle, d'ajustage et de coupe qui viennent d'être décrites sont répétées pour la brame 2 chargé sur cet autre poste de travail.During the time that has passed until stopping the flame cutting of slab 2, another slab 2 has been loaded on the second workstation following the procedure which has just been described. The operation oxycutting of the first slab 2 finished, rules 7, 8 are moved with the flame cutting torch 2 and the deburring device to the other workstation including the support frame 4 forms an identical angle with respect to vertically as the support frame 4 of the first station work on which the flame cutting operation has just taken place finish. So said rules 7, 8 can be moved in jumper on the support frame 4 of the other station of work where the charged slab 2 is to be cut and the same control, adjustment and of cutting which have just been described are repeated for the slab 2 loaded on this other workstation.

    Entre-temps le cadre support 4 du premier poste de travail a été abaissé dans la position horizontale et la brame 2 coupée a été enlevée par ledit moyen de manutention. Une autre brame 2 à couper est chargée sur ledit cadre support 4. Le dispositif 1 l'oxycoupage décrit permet de couper des brames 2 suivant un procédé continu. Si un procédé non-continu est suffisant, il et possible de ne prévoir qu'un poste de travail ayant un endroit de parcage pour ladite au moins une paire de deux règles 7, 8 pendant le chargement et déchargement des brames 2 sur le cadre support 4 unique.Meanwhile support frame 4 of the first station working has been lowered to the horizontal position and the cut slab 2 was removed by said means handling. Another slab 2 to be cut is loaded on said support frame 4. The device 1 the flame cutting described allows slabs 2 to be cut using a continuous process. If a non-continuous process is sufficient, it is possible to only provide a work station with a place for parking for said at least a pair of two rules 7, 8 during the loading and unloading of slabs 2 on the single support frame 4.

    Suivant les besoins, c-à-d. si on veut exécuter en même temps sur une brame 2 plus d'une opération de découpage, on peut prévoir plus qu'une paire de règles 7, 8 mobiles en cavalier sur le cadre support 4 et les chalumeaux d'oxycoupage 2 et dispositifs d'ébavurage associés nécessaires ; ainsi une paire supplémentaire 7, 8 est représentée dans les figures 1, 2 et 3.As required, i.e. if we want to execute at the same time on a slab 2 more than one operation of cutting, we can provide more than a pair of rules 7, 8 mobile in jumper on the support frame 4 and the flame cutting torches 2 and deburring devices partners required; plus an additional pair 7, 8 is shown in Figures 1, 2 and 3.

    Le dispositif décrit ne permet que difficilement de refendre une brame 2 par oxycoupage. A cette fin on peut prévoir entre les deux postes de travail qui viennent d'être décrits et en ligne avec ceux-ci un troisième poste de travail à cadre support 4 ajustable dans une position de travail entre -20° et -10° par rapport à la verticale, mais non nécessairement basculable jusqu'en position horizontale, mais pour le reste identique aux deux autres postes décrits plus haut. Un tel dispositif est représenté de façon schématique dans la figure 4.The device described only allows it is difficult to split a slab 2 by flame cutting. AT this can be done between the two workstations which have just been described and in line with these a third workstation with support frame 4 adjustable in a working position between -20 ° and -10 ° relative to the vertical, but not necessarily tiltable horizontal position, but for the rest identical to both other positions described above. Such a device is shown schematically in Figure 4.

    Dans le mode de réalisation de la figure 4, les règles 7, 8 avec le chalumeau d'oxycoupage 3 et le système d'ébavurage associé sont en principe mobiles sur le cadre support 4 du troisième poste de travail, tout en pouvant être déplacés sur les deux autres postes pour des travaux particuliers possibles. En plus, dans ce mode de réalisation, les rouleaux 6 inférieurs ou une partie en moins de ces rouleaux, peuvent être motorisés pour déplacer la brame 2, après avoir été chargée sur le poste fonctionnant pour le chargement, vers le troisième poste de travail pour l'oxycoupage de la brame, et déplacer la brame 2 ensuite vers le poste suivant fonctionnant pour décharger la brame 2 coupée. Comme dans le mode de réalisation décrit en rapport avec les figures 1 à 3, les cadres support 4 des postes extrêmes peuvent être rabattus dans la position horizontale pour le chargement d'une brame 2 sur les rouleaux 5 ou le déchargement d'une brame 2 coupée des rouleaux 5.In the embodiment of FIG. 4, the rules 7, 8 with the flame cutting torch 3 and the system associated deburring are in principle movable on the frame support 4 of the third workstation, while being able be moved to the other two positions for work individuals possible. In addition, in this mode of realization, the lower rollers 6 or part thereof fewer of these rollers, can be motorized to move slab 2, after being loaded on the station operating for loading, to the third station work for the flame cutting of the slab, and move the slab 2 then to the next station operating to unload slab 2 cut. As in the described embodiment in connection with FIGS. 1 to 3, the support frames 4 of extreme positions can be folded into position horizontal for loading a slab 2 on the rollers 5 or the unloading of a slab 2 cut from rollers 5.

    Le nombre de paires de règles 7, 8 dépendra du nombre de pièces de brame à réaliser à partir d'une brame 2 à refendre. Avant de refendre une brame, il est également possible de d'abord débiter la brame 2. Le mode de réalisation représenté à la figure permet donc de soit débiter, soit refendre, soit aussi débiter et refendre des brames en continu.The number of pairs of rules 7, 8 will depend on the number of slab pieces to be made from a slab 2 to split. Before slitting a slab, it is also possible to first charge the slab 2. The mode of embodiment shown in the figure therefore allows either debit, either resell, or also debit and resell continuous slabs.

    Un mode de réalisation supplémentaire d'un dispositif d'oxycoupage de brames est représenté aux figures 5 et 6. Le dispositif d'oxycoupage comprend une aire 12 de chargement de brames 2, aire 13 de travail où l'oxycoupage des brames 2 est réalisé à l'aide d'un chalumeau d'oxycoupage 15 auquel fait face un dispositif de d'ébavurage 16, et une aire 14 de déchargement de la brame 2 coupée. Lors de l'opération d'oxycoupage la brame 2 passe en position horizontale entre le chalumeau d'oxycoupage 15 et le dispositif d'ébavurage 16 sur des rouleaux de support 17. L'ensemble chalumeau 15 et dispositif d'ébavurage 16 se trouve entre deux rouleaux de support 17 et est mobile en direction axiale des rouleaux 17 transversalement à la brame 2 d'un bord longitudinal à l'autre bord longitudinal pour débiter la brame 2 au repos pendant l'oxycoupage, ou pour ajuster le chalumeau d'oxycoupage 2 en un endroit précis entre les deux bords longitudinaux de la brame 2 pour refendre la brame 2 se déplaçant en direction longitudinale sur les rouleaux 17 pendant l'opération d'oxycoupage.An additional embodiment of a slab flame cutting device is shown in Figures 5 and 6. The flame cutting device comprises a slab loading area 12, work area 13 where the flame cutting of the slabs 2 is carried out using a flame cutting torch 15 which is facing a deburring 16, and a slab unloading area 14 2 cut. During the flame cutting operation, slab 2 passes in horizontal position between the flame cutting torch 15 and the deburring device 16 on support rollers 17. The torch 15 and deburring device 16 assembly between two support rollers 17 and is movable in axial direction of the rollers 17 transversely to the slab 2 from one longitudinal edge to the other longitudinal edge to cut slab 2 at rest during flame cutting, or to adjust the flame cutting torch 2 in one place precise between the two longitudinal edges of the slab 2 to split slab 2 moving in the direction longitudinal on the rollers 17 during the operation flame cutting.

    Dans l'aire de chargement 12, aussi bien que dans l'aire de déchargement 14 on peut prévoir une table élévatrice 18 ou 19 ajustable de sorte que le plan de la table 18 ou 19 ou le plan supérieur d'une brame 2 ou d'une pile de brames se trouve dans le plan formé par les rouleaux 17. Un moyen pousseur 20 hydraulique ou mécanique est prévu pour pousser la brame 2 de la table 18 ou brame 2 supérieur d'une pile de brames sur la table élévatrice 18 dans et à travers la zone de travail 13. Aussi certains des rouleaux 17 peuvent être motorisés pour transporter la brame dans et hors de l'aire 13 de travail dans l'aire 14 de déchargement ou un autre moyen pousseur ou de manutention, non représenté, enlève la brame ou une pile de brames. La table élévatrice 19 est ajustable en hauteur de sorte que son plan ou la surface supérieure d'une brame 2 sur la table 19 se trouve dans le même plan que le plan formé par les rouleaux de support 17 pour recevoir la brame 2 coupée, c-à-d. débitée ou refendue.In loading area 12, as well as in the unloading area 14 a table can be provided lift 18 or 19 adjustable so that the plane of the table 18 or 19 or the upper plane of a slab 2 or a pile of slabs lies in the plane formed by the rollers 17. A hydraulic or mechanical pusher means 20 is provided to push slab 2 from table 18 or slab 2 top of a stack of slabs on the lift table 18 in and through work area 13. Also some of the rollers 17 can be motorized to transport the slab in and out of area 13 working in area 14 unloading or other pusher means or handling, not shown, removes slab or pile of slabs. The lifting table 19 is adjustable in height from so that its plane or the upper surface of a slab 2 on table 19 is in the same plane as the plane formed by the support rollers 17 to receive the slab 2 cut, i.e. debited or resold.

    La figure 6 est une représentation schématique d'une variante du dispositif d'oxycoupage de brames selon la figure 6. Le train des rouleaux de support 17 est prolongé de part et d'autre de l'aire 13 de travail dans les aires de chargement 12 et 14 et les tables élévatrices 18, 19 sont placées à côté des rouleaux de support 17 dans lesdites zones de chargement 12 et de déchargement 14. Le niveau desdites tables ou la surface supérieur des brames déposées sur elles se trouvent dans le même plan que le plan de support formé par les rouleaux de support 17.Figure 6 is a schematic representation of a variant of the slab flame-cutting device according to Figure 6. The train of support rollers 17 is extended on both sides of work area 13 in loading areas 12 and 14 and lifting tables 18, 19 are placed next to the support rollers 17 in said loading 12 and unloading zones 14. The level of said tables or the upper surface of the slabs deposited on them are in the same plane as the support plane formed by the support rollers 17.

    Cette variante représentée à la figure 6 du mode de réalisation de la figure 5 permet le refendage aisé et rapide d'une brame 2 tout en permettant également le débit de brames 2 pour le fait de pouvoir déplacer le chalumeau d'oxycoupage 2 transversalement à l'extension longitudinale d'une brame 2 d'un bord longitudinal vers l'autre bord longitudinal de la brame 2, déplacement également requis pour ajuster différentes largueurs des morceaux de brame refendue.This variant shown in Figure 6 of embodiment of Figure 5 allows easy slitting and quick of a slab 2 while also allowing the slab rate 2 for being able to move the flame cutting torch 2 transversely to the extension longitudinal of a slab 2 from a longitudinal edge towards the other longitudinal edge of slab 2, displacement also required to adjust different widths of pieces of split slab.

    La brame 2 refendue est poussée par un moyen pousseur 10 de la table 18 de l'aire de chargement 12, en direction de la flèche 23 sur les rouleaux 17, qui la transportent vers et à travers l'aire de travail 12 où la brame 2 est, p.ex., refendue en trois morceaux de brame de largeurs égales ou différentes à l'aide de chalumeaux d'oxycoupage 15. Le transport de la brame 2 continue en direction de la flèche 22 sur les rouleaux 17 dans l'aire de déchargement 14 ou les morceaux de la brame refendue sont poussés par le moyen pousser 21 en direction de la flèche 24 sur la table 19 de l'aire de déchargement 14.The split slab 2 is pushed by a means pusher 10 of table 18 of loading area 12, in direction of the arrow 23 on the rollers 17, which transport to and through work area 12 where the slab 2 is, for example, split into three pieces of slab of equal or different widths using torches flame cutting 15. The transport of slab 2 continues in direction of arrow 22 on rollers 17 in the area unloading 14 or the pieces of the split slab are pushed by the means pushing 21 towards the arrow 24 on the table 19 of the unloading area 14.
